Anatomy of human digestive system

[sathyanarayanan]

Any one can give pH values at various place in our digestive process, and also how much time take to travel an tablet from mouth to posterior colon and rectum.
I want data about length of small intestine and large intestine

Thanks

Um...what I know is the pH inside the ventriculus which is about 2 till 2,5.
when it comes to intestinum tenue the pH is raised again at about 6.5 till 8.5 (if my memory serves me right).
About the length of small intestine...I think it's about 5 metres and the big one is shorter than that..

[MrMistery]

The stomach Ph is 1-2.5
The small intestine PH is 7-8.5
The small intestine has ~4-6 meters
The big intestine has ~1.5 meters
